To all whomtzl' may concern:

Be it known that l, CHARLES F. Fonsren, a citizen of the United States, and a resident of the village of @ak Park, in the county of Cook and State of illinois, have invented ay new and useful 1improvement in Vehicle- Tires, of which the following isa speciea tion. v r

My invention relates to 'vehicle tires, and .has for its special object the provision `of tire in which the tread, or that portion which is subject to Contact with the road and the wear whichk is incident to such Contact, separable und may be renewed as occasion may require.

l attain the above object by means of tee structure illustrated in the accompanying drawing, in which:

Figure l is a transverse section through a vehicle tire embodying my improvement; Fig. Q is a transverse section through a modified tire construction embodying myy invention, and Fig. 3 is an elevation oi a wheel equipped with my invention, i is a detail oie the spring or tension means ifor securing Vthe opposite ends of the retaining rod.

Similar reference characters refer to similar parts throughoutV the views c Any form of wheel may be employed and any of the usual modes of assembling -the tire il'seli:` with the Wheel may also be einployed. i f

s illustrative of my'invention l have shown an ordinary eleneher assembly, and a tire with 'a form of spring filler. in the oleneher structure there is provided a elencher rim l upon the elly'Q of the wheel 3. The tire consists of the outer easing i which is oi. the usualeircular cross section, the longitudinal meeting edges whereof are provided with the olenoher ribs 5 which engage the oleneher rim 1, as clearly shown in Fig. l. Inside of the easing fi is the usual inner or air holding tube, 4a.

My invent-ion consists in providing' the outer portion 0r tread of the easing with an annular depression or channel', the 'Walls 'forming the edges of which may be preferaoly beveled toward the center so as to give the depression 6 a wider dimension upon. the bottom than upon the top. Into the depres- Speecation of Letters latent.

sion (i is inserted the tread 7, which may be made of the ordinary fabric of which casings for tires are at present made, or of any" desired material.. The edges of the tread are beveled at 8 toY fit into the beveled sides7 of the depression 6 so as to secure the bottom of the insert irmly to the easing. The tread 7 should be of such thickness as to bring it such a distance above the surface of the 'easing' as to receive all of the Contact with the road.

ii the modified. .form of my invention shown in 2, the tire, instead of having an air holding tube, 42, is providedwith a spring filler, l, about which extends a easing, in the tread or" the casing, 4', just as in u easing for a pneumatic til i. is provided an annular channel 6 into which is inserted a tread 7 similar in all respects to the channel 6 andtread 2' heretofore described. The tread or insert 7 is further severed in position by vmeans of the tread retaining bands 9 which extend entirely around the tire and telly and the ends whereof are provided with eyes which are brought into alinement `:it one side of the iellyn The bands 9 maybe given any desired shape so as to eet as a preventive against slipping' or siziddingas Well es for retaining the tire and insert in position. Any desired number oi' the bands may be disposed. about tl e tire, and, after they are in position, rod ll is passed 'through the alining eyes l() of the various bands. The endsy of ythe rod il may be secured together inany desired way, but preferv to hold them together by some spring or yielding means which will put the several bands under a tension. Such a red coupler may consist of a box 12, shown in Fig. e, -into which box one end or" the said rod extends. This endv may be provided 'with a spring 13. -The other end o' the rod is passed through alining holes 'ill provided in the box 12, parallel with theigsaid spring?. The end of the rod which passes through the alining holes is' threaded and an adjusting screw, 15, is provided in the box 12 between the aliningv holes 1li by means of which the rod 11 may be given any desired tension.

Having deseribed my invention what .T
